Hotfix 15

49778 - Additional user restrictions for phone calls

Components: All Products

Background:
Functionality of a handset can be limited via several parameters under Customization/Visibility and Customization/Phone Restrictions.
Further restrictions have been requested:
* Restrict loudspeaking mode during call.
* Do not display any name or number information of the other party in a call.
* When keys 0-9, * and # are disabled, it is not possible to use DTMF signaling during call. Make it possible to use those keys only during call.

Solution:
New parameters and parameter values are available under Customization/Phone Restrictions.

49780 - Changed German translations

Components: All Products

Background: Since the current German translation is using the same term for both "Messaging" and "Inbox" we would
suggested change of translation for "Inbox" that could be also translated as "Eingang".
"Transfer" is also translated inconsistently and sometimes incorrectly when German language is used.

Solution: Minor corrections in the German translations.

49777 - Combine local phonebook result with calling party number for incoming calls

Components: All Products

Background:
For an incoming call that has been diverted via one party, the handset will display both the calling number and
diverting number/name.
In case the calling number is present in the Contacts/local phonebook, the diverting number/name is
replaced by the name of the calling number found in the phonebook. It is important to able to see that the call
is not direct to the user, but diverted from another party.

Solution:
Display number of calling party for incoming call together with Diplay Management text or CNIP if configured.
New parameter "System->System [A..H]->Display calling number together with name" is now available. If
Display Management text is not already combined with found phonebook name (according to parameter
"Display Management and Local Phonebook Name"), the calling party number will be displayed as well.
If Display management is not available in the system, the calling number may be combined with found
phonebook name or with CNIP (calling party name).

49781 - Configurable Bluetooth audio transfer question for outgoing calls

Components: All DH7 Products

Background:
When starting a new outgoing call with a connected Bluetooth headset, the user will be informed that the
audio is routed through the headset and the user can choose to transfer the audio back to the handset. This
popup is shown for 8 seconds and possibly blocking information to the user such as name or number of the
other call party. Make it configurable to show this popup, with a default setting of no popup screen shown.

      Solution: 
      Threshold is increased to deny a certain amount of packets from an “old” device after doing media re-routing

      100738 - IP62 stay in Messaging Only mode for several hours

      Background: 
      The handset is not trying to contact the PBX for registration which leads to Messaging only text in the display.  

      Solution: 
      The SIP-stack is modified to detect the PBX and register to it. 

      100734 - IP62: Corrupt voice packages from the other device disconnects the call

      Background: 

      If a called device sends corrupt voice packages the call is disconnected. 


      Solution: 

      It is now possible to call a device that is occasionally sending corrupt voice packets.  

      100732 - IP62: Inefficient scan result handling cause audio problems during location scanning

      Background: 

      There is a general problem in IP62 when running in world mode on 5 GHz. The Wi-Fi driver performs unnecessary processing of each incoming probe response, and during this processing it is unable to transmit or receive data, for instance RTP. It is possible to end up in a situation where processing the probe responses generated by a 20 ms active scan of a channel takes more than 20 ms; i.e. no RTP data is transferred until the scanning round is completed.   It is especially problematic when location scanning is enabled, since the handset will then send broadcast probe requests for any SSID and hence receive many more probe responses. But the effect is also present and might cause audio jitter when location is not enabled. 


       Solution:

       Probe response handling has been optimized so that it does not affect voice quality.  

      100739 - IP62: No name in display with redirected calls and long caller ID (> 28 characters)

      Background: 
      If the name of diversion is longer than 28 characters, example 29 chars, nothing is seen.  


      Solution: 
      If the string is too long then all characters that fit the screen is now copied and aligned so that callerID of original caller is seen. 

      100735 - IP62: Speech delay

      Background: 
      Intermittent audio delays and/or dropouts during call. 
       
      Solution: 
      The DSP was not able to handle voice packets too near in time after control packets has been sent to it. A small delay was inserted to between sending of control data and voice data to DSP  

      100733 - IP62: Unable to call to phone number that include space

      Background:
      It is not possible to make a call to a number that includes blank spaces. 

       

       It is possible to make a call if the number from the phone book has no spaces as in e.g. "+4951398984504".
      It is not possible to make a call if the number in the phone book includes blank spaces as in e.g. "+49 5139 898 4504". The handset dials only the digits before the first space, e.g. +49. 

       

       Solution: 
      Phone number that includes spaces after receiving it from the phone book application is now possible to use since the spaces are removed before presenting it for the user.

      IP64/IP65 2.12.10

      120498 - IP64/IP65 A tinny voice and reverberation/echo are heard at the receiving end when a person stops talking

      Background:
      During conversation via a handset, the receiving end experiences the "robotic sound" and reverberation/echo when the emitting end stops talking. It is not loud and not obvious but can be annoying to end-users.

      Solution:
      Fixed a problem with tinny voice and reverberation/echo are heard at the receiving end.

      120496 - IP64/IP65 Default setting change for "Display Management and Local Phonebook Name" parameter

      Background:
      Some customers require having the number/name resolution of a calling party shown on the handset. The setting of the parameter "SystemX/Display Management and Local Phonebook Name“ with „Add name internal and external call“ value by default allows them to achieve this goal without additional actions.

      Solution:
      The default value of the parameter "SystemX/Display Management and Local Phonebook Name“ is set to „Add name internal and external call“. This change is system dependent.

      120499 - IP64/IP65 Incorrect French translation of "No Access" and "No System"

      Background:
      The French translation of "No Access" and "No System" messages is incorrect in the DECT handsets.

      Solution:
      Fixed incorrect French translation of "No Access" and "No System" messages.

      115308 - IP64/IP65 New parameter to set minimum allowed volume for handset system sounds

      Background:
      There is a new parameter 'Minimum allowed volume' introduced to restrict the lowest level of sound on a handset. This parameter can be configured via WinPDM. ‘Minimum allowed volume’ connects to the existing parameter ‘Turn off sound’ and works in the following way: When the option 'No' is chosen for the ‘Turn off sound’ drop-down list, it is possible to set up the 'Minimum allowed volume' parameter value from 1 to 7. If a user tries to decrease a value level lower than defined by the ‘Minimum allowed volume’ parameter, the following pop-up will warn they that it is restricted: "Volume reset to the lowest level allowed".

      Solution:
      New parameter called “Minimum allowed volume” is introduced to let an administrator prevent users from setting volume level lower than allowed.

      115306 - IP64/IP65 No access displayed on handsets when roaming

      Background:
      From time to time the handsets at the site displays "No access" when moving between the Base stations in the systems using Multicast groups Restart of the handset temporarily solves the problem.
      The "No access" annunciator is visible from 2 to 40 seconds. It is possible to call the handset also when "No access" is shown.

      Solution:
      Fixed a problem where handsets could show the 'No access' message on screen when moving between the Base stations in the systems using Multicast groups.

      115309 - IP64/IP65 No indication of stopped charging on a switched OFF device when the temperature is out of bounds

      Background:
      When the charging is stopped by HW due to the temperature is out of bounds, there is no indication on the screen that it was stopped if the device is switched OFF.

      Solution:
      A new special icon is shown when the charging stopped on the switched OFF device due to temperature out of permitted bounds.

      120497 - IP64/IP65 Phone numbers with space and "-" wrongly translated when dialing from LDAP central phone book

      Background:
      When a handset is using LDAP Centralized phonebook, phone numbers that containing space or "-" are correctly displayed in the handset, but when dialing, the space and "-" are not filtered out from the dial string and translated to digits. As a consequence, the end-user dials the wrong number.

      Solution:
      Fixed the problem with incorrect translation of space or “-“ in phone numbers when dialing from the LDAP Central phonebook.

      115310 - IP64/IP65 Pop-up 'Battery temp critical, charging disabled' displayed clipped for some languages

      Background:
      On the idle screen, the pop-up 'Battery temp critical, charging disabled' displayed clipped for Russian, German and Arabic languages.

      Solution:
      Fixed a problem where popup is cut off in Russian, German and Arabic. The popup displays correctly now.

      115303 - IP65 Manual key lock displays "Call" instead of "Lock"

      Background:
      When a user presses *, on the handset display, the soft key function appears as following: "call" for a short time, then "lock", and after a couple of seconds "call" again. This behavior could cause the problem for a user to make a call instead of locking the handset when pressing the soft key quickly after *.
      The expected behavior for this use case is when pressing * on the keypad the left soft key shall display "lock" and then after a couple of seconds "call".


      Solution:
      Fixed a problem where the wrong sequence of the soft key functions on the handset could cause a phone call instead of key lock.

      115307 - IP65 Received Interactive Messages not being displayed sometimes

      Background:
      Interactive Messages are sometimes not being displayed as a pop-up notification in the handset. Once the problem occurred, each 30th message will not be displayed as a pop-up notification. Messages not displayed appear in the inbox after a handset restart.

      Solution:
      Fixed the timing problem with “Time to live” expiration and receiving a new IM message that caused an issue that the IM message is not displayed.

      IP73 3.0.0

      110738 - Allow SCEP certificate to be used for SIP TLS and add new 'Automatic' certificate choice

      Background:
      Even if a device certificate had been provided to the handset through SCEP enrollment, it is not possible to select this certificate to be used for SIP TLS connections.

      At the same time, choosing which certificate to use for EAP and SIP TLS is also possible to simplify by removing the choices 'Self-signed' 'SCEP' and 'Production certificate' and replacing them with the new setting 'Automatic'.

      Solution:
      The parameters EAP client certificate and SIP TLS client certificate can now be set to "Automatic".

      With this setting, a certificate received through SCEP enrollment will be used if it exists, otherwise a built-in certificate will be use (not available for all handset models). If neither certificate type is available, no client certificate will be used for EAP, and a automatically generated and self-signed certificate will be used for SIP TLS (a certificate is required for SIP TLS in order to receive incoming TLS connections from the SIP proxy).

      The handset will continue to function as before after upgrading to this software, even if one of the now removed parameter values was configured. The device manager will however not allow saving of any other changes until the parameter is

      110726 - Authentication fails when both Fast BSS Transition and Protected Management Frames are enabled

      Background:
      WPA2-Enterprise authentication fails when both Fast BSS Transition and Protected Management Frames are enabled

      Solution:
      Handset will associate and roam in system where both 11r and 11w are enabled.

      110718 - Configure Out Of Memory killer and dump the memory usage

      Background:
      If handset for some reason runs out of memory the handset will freeze and be unable to use. The only way to recover is to remove the battery.

      Solution:
      The Out Of Memory (OOM) killer is configured to reboot the handset when no more free memory exists.
      Before the handset reboots the memory usage is dumped to internal trace in the phone and to an external syslog server.

      110712 - Create an adjustable threshold for starting of SCEP renewal

      Background:
      It must be possible to set a threshold for when a renewal of the SCEP certificate shall start. Currently the threshold is set to 20% of the validity period and is not configurable.

      Solution:
      New user parameter “Renew threshold” in /Device/SCEP/

      110716 - Deauth on roam

      Background:
      When roaming some Wi-Fi systems might require the handset to notify the old AP that it is leaving.

      Solution:
      With a user parameter it is now possible to enable/disable sending deauthentication frame to current AP.

      110748 - Enabling SFTP does not have any effect

      Background:
      Changing any SFTP user parameter have no effect until the handset is restarted. This means that SFTP is not used when turned on, and still used when turned off.

      Solution:
      Changing any SFTP user parameter now automatically restarts the handset.

      110737 - Factory reset sometimes not working

      Background:
      When performing factory reset, the handset restarted and "Unexpected restart" was displayed. The factory reset was unsuccessful.

      Solution:
      Factory reset is made more robust. If factory reset fails, this is now detected, and a new try is made automatically at next startup.

      110713 - Improved 802.11k support

      Background:
      When 802.11k is enabled in the handset, only the Wi-Fi channels received as part of the 802.11k neighbor list from the AP will be scanned primarily. If this did not yield a roaming candidate, previous software versions would fall back to scanning all channels that are allowed in the Wi-Fi regulatory domain. This would often affect voice quality during call.

      Solution:
      The option to enable 802.11k has been moved from the "5 GHz channels" parameter to a separate parameter. This means that the "5 GHz channels" parameter can now be used to select which channels shall be scanned when scanning the neighbor list is not sufficient.

      110715 - Improved handling of CAC/TSPEC reject from AP

      Background:
      When CAC/TSPEC is enabled, and the current access point rejects the handset's request to allocate bandwidth for a call, the handset will need to roam to a different access point.

      Solution:
      The roam to a new access point will now be performed quicker, resulting in less disruption of an ongoing call.

      110711 - Indicate that the SCEP procedure has failed

      Background:
      Sometimes a new certificate cannot be installed due to some constraints. If such a case happens repeatedly, the user must be notified that admin should be contacted (popup that user must acknowledge). The admin should investigate the syslog for the reason.

      Constraints:

      * Certificate has a shorter validity period than 1 hour.

      * SCEP server validation failed

      * Erroneous SCEP parameters from user params or DHCP

      * Received certificate could not be saved to file system

      Solution:
      If SCEP fails repeatedly the following popup text is displayed once per 24 hours: "SCEP failed. Contact handset admin for help" When renewal fails and the existing certificate is due to expire in 24 hours or less, the following popup text is displayed once per hour (more frequently last hour): "SCEP certificate expires soon. Contact handset admin"

      110733 - Loudspeaker not working after remove from charger

      Background:
      After the handset been removed from the charger, only "popping " sounds are heard from the loudspeaker if any audio is played. The handset had key sound enabled and "In charger action" set to "Sound off". After answering an incoming call everything works again.

      Solution:
      If the handset was put in charger during a call and the in charger action parameter was set to "Sound off" the loudspeaker stopped working. This problem is now solved.

      110714 - Migrating to and from older software versions:

      Background:
      If the "5 GHz channels" parameter was set to 802.11k prior to upgrading to this software version, the new parameter "Use 802.11k neighbor list" will be automatically set to Yes by the new software. For optimal performance it is important to update the "5 GHz channels" parameter after the upgrade, so that it only contains the channels actually used in the system.

      Solution:
      If downgrading to an earlier software after this change, 802.11k will have to be
      enabled again using WinPDM.

      110736 - Noise suppressing not working for all frequencies

      Background:
      It looks like suppressing noise mechanisms in the handset is not affecting noise between ~5500Hz and ~6700Hz. A test is done with a G722 wide-band call.

      Solution:
      Noise suppressor performance improved.

      110710 - Opus narrowband

      Background:
      Customer request to add Opus narrowband

      New feature:
      It is now possible to configure to use Opus narrowband

      110717 - Parameter for removing outdated security protocols and algorithms

      Background:
      TLS protocol versions 1.0 and 1.1 and SHA-1 (when used for certificate signature validation) are no longer considered fully secure and shall be possible to disable.

      Solution:
      A new parameter "Allow outdated security protocols" has been added under DEVICE -> General. If set to No, all TLS connections will be established using TLS 1.2 or higher and SHA-1 may not be used for certificate signature verification. Additionally, some weak crypto algorithms with short key lengths will be disabled. For backwards compatibility reasons, the default value of the new parameter is "Yes".

      110747 - Personal phonebook synchronization sometimes fails

      Background:
      Importing contacts (using "Import contacts->") from WinPDM does not work 100%. Sometimes the uploaded contacts do not appear in the handset and sometimes some of the existing contacts in the handset are still there after the upload (they shall be deleted).

      Solution:
      There were problems with the synchronization between the handset and WinPDM, that is now fixed.

      110734 - Problem with background noise growing more and more when using handsfree

      Background:
      When having a conversation between two parties where both are using handsfree and using either codec G711 or G722, the background noise is growing and growing (like it is diverging ) and after around 2-3 minutes of communication, you cannot hear the remote party anymore because the background noise is too loud.

      Solution:
      Noise suppressor is now activated in handsfree mode to avoid growing background noise. Noise suppressor limits are also corrected to remove very low and high frequency noise.

      110723 - Problem with TSPEC causes problems with SIP telephony

      Background:
      Issues with dropped calls and not being able to make calls when CAC/TPSEC is enabled have been reported.

      Solution:
      An issue was identified and fixed in the CAC/TSPEC implementation.

      110732 - Problems with audio transfer from Bluetooth headset to handset indication 'Audio in headset. Transfer to phone?'

      Background:
      Several problems:

      * The indication for audio transfer from headset to handset “Audio in headset. Transfer to phone?” does not disappear after 10 seconds as it should.
      * The soft keys Yes and No is switched.
      * If having screen saver active when “Audio in headset. Transfer to phone?” popups, soft key presses goes to the screen underneath instead to the popup

      Solution:
      Properly close audio transfer screen after 10 seconds and the soft keys now show correct information and applies to correct screen.

      110721 - Reduce the number of NTP requests

      Background:
      It was discovered that the handset would sometimes perform NTP time synchronization as often as multiple times per minute.

      Solution:
      NTP time synchronization is now performed once per 24 hours.

      110730 - Remove support for RFC4361 in DHCP

      Background:
      The handset generates Option 61 client identifiers according to RFC4361 when creating DHCP requests. This seems to be incorrectly handled by some DHCP servers (which do not support this RFC), causing multiple IP addresses to be allocated per handset.

      Solution:
      Since the handset is able to function just as well without RFC4361 support, it has been disabled.

      110740 - SCEP - Certificate is not renewed when certificate parameters are changed

      Background:
      The certificate is only renewed when it has expired, it should also be renewed when any of the following user parameters are changed:
      Country Code
      Organization name
      Unit name
      State Name
      Common Name

      Solution:
      The certificate is renewed when any of these parameters is changed.

      110739 - SCEP handling can hang if unsuccessful procedure

      Background:
      If a SCEP procedure fails for some reason, there are dependencies to receive a new lease info from DHCP to trigger a new attempt. These dependencies can make the SCEP handling hang since new lease info from DHCP are rare.

      Solution:
      Removed dependencies to receive a new lease info from DHCP to trigger new attempt if SCEP procedure fails.

      110744 - SCEP: Certificate is renewed even though the SCEP URL is empty

      Background:
      When SCEP URL is removed from the configuration (by DHCP or user parameter) the handset still renews certificate after restart.

      Solution:
      Active SCEP URL is cleared and an automatic restart is triggered (twice if SCEP URL was set by user parameter). After the restart(s) the handset does not renew the certificate.

      SCEP: Handset stopped renewing certificate when loosing WiFi connection
      Background:
      If expiry check is run when handset has lost WiFi connection it does not renew certificate when WiFi connection is regained.

      Solution:
      Renewal is triggered, if needed, when WiFi connection is regained.

      110742 - SCEP: Changed behavior of 'validate server certificate' parameter

      Background:
      When the parameter ‘Device/SCEP/Validate server certificate’ was set to Yes, the handset would require a trusted certificate that match the certificate provided by the SCEP server to be installed, otherwise no connection would be established to the SCEP server.

      Solution:
      In order to make easy deployment of new handset easier, the handset will now accept any server certificate from the SCEP server if no trust certificates are installed in the handset. Since a successful SCEP enrollment will result in a trust certificate to be installed in the handset, this amounts to a Trust On First Use (TOFU) approach.

      110743 - SCEP: If certificate expires or is revoked, the handset does not try to get new certificate

      Background:
      When a certificate expires or is revoked, there is no possibility to get a new certificate if SCEP is configured by user parameters.

      Solution:
      When a certificate expires or is revoked, the handset will try to get a new certificate.

      110746 - SCEP: Late received certificate and retry timer when less than one hour left are not handled correctly

      Background:
      When a new certificate arrives later than renewal threshold it is rejected. It can be accepted instead and a renewal can be triggered to get a new one. When renewal fails for some reason a new try is done in one hour. When the validity left of current certificate is less than one hour this time must be shorter.

      Solution:
      Late received certificate is accepted if there is time left on validity period. When there is short time left and communication fails with SCEP server, the retrial attempts are done with shorter interval then one hour.

      110741 - SCEP: The renew timer can stop during certificate renewal

      Background:
      If the timer for renewal check is triggered during certificate renewal, the renewal check is not done and the timer is not retriggered.

      Solution:
      If the timer for renewal check is triggered during certificate renewal, a new renewal check will be done in one minute.

      110719 - Show external caller ID prior to answer

      Background:
      Customer request to display the external caller’s ID prior to answer. This is happening now: When an external call is transferred from an ELG IP handset to the handset, the caller ID shows the internal station number of the transferring handset (and not the caller ID of the external caller). When you answer the call, the external caller’s CLI is displayed.

      Solution:
      Possible to see external caller ID prior to answering of the call

      110722 - SIADDR field in DHCP response sometimes not handled correctly

      Background:
      The DHCP server send out a response (DHCPACK) to a request sent by the handset. This DHCPACK can contain several different parameters/options and IP addresses to different services that the handset requested. One of these options is the SIADDR(Server IP address) field. In the scenario only the SIADDR field is used and the IP address contains a single 0, for example 1.10.0.58 this will be read incorrectly and handset will not be able to continue and connect to the server.

      Solution:
      Fixed where handset would not read a server IP address formatted in a certain way correctly; if this IP was delivered to handset with a DHCP response using the "next server"/SIADDR field. This made the handset unable to connect to server in a scenario where SIADDR was the only address field used.

      110729 - SIP 301 Permanently Moved failover issue

      Background:
      When two SIP servers were used for redundancy, the handset would not under some circumstances not failover to a secondary SIP server a second time without having restarted in between.

      Solution:
      Failover now works as expected.

      110720 - SIP Registration not renewed in time

      Background:
      The handset would not always renew the registration to the SIP proxy before it expired. This could cause a short loss of telephony service.

      Solution:
      A situation where the SIP register message would not be sent correctly has been identified and resolved.

      110749 - TemplatesFilename is missing in packageinfo.inf

      Background:
      The information file which is part of the software package file does not contain any tag named "TemplatesFilename" which causes the GDPR template not being loaded into the WinPDM when the software package file is loaded.

      Solution:
      GDPR template file is now possible to import into WinPDM.

      110731 - Too late renewal of IP address if DHCP server does not specify renewal and rebind time

      Background:
      If a DHCP was not configured to specify renewal and rebind times in its offers, the handset would not renew its DHCP lease until it expired, which could a brief loss of network connectivity.

      Solution:
      The handset will now use default renewal and rebind times according to RFC2131, which ensures that the DHCP lease will be renewed before it
      expires.

      110725 - U-APSD Wi-Fi power save used even if not supported by AP

      Background:
      U-APSD is expected to always be available in the Wi-Fi systems where the handset is used. It is the recommended power save method for optimal voice quality and call time performance.

      If, for some reason, U-APSD support is not indicated by the access point, U-APSD would still be used by the handset, resulting in very bad voice quality during calls and general network connectivity issues.

      Solution:
      The handset will now fall back to using legacy power save when the AP does not indicate support for U-APSD. This will reduce the standby and talk time of the device.

      110724 - Uploaded client certificates could not be used for SIP over TLS

      Background:

      The syslog entries  "Call start -some enviroment info-" and "Call ended -some enviroment info-" are sometimes missing in the syslog.
      The issue happens mostly when making very short calls.

      Solution:
      Syslog entries when call is started and stopped are now always included in the log.

      119259 - IP73 WLAN sometimes fail to retrieve IP address

      Background:
      The handset would not always recover from a situation where it was associated to a WLAN but was not able to send DHCP requests to retrieve its IP address.

      Solution:
      The WLAN connection supervision has been reworked so that it will reinitialize the WLAN connection in order to recover from this situation.

      119255 - IP73 WLAN: OKC roaming not working together with 802.1X-SHA2 authentication key management

      Background:
      Roaming using Opportunistic Key Caching (OKC) did not work correctly when 802.1X-SHA2 was enabled in the WLAN controller.

      125784 - 40 and 80 MHz does not work for radio tests

      Background:
      When selected 40 MHz or 80 MHz for "Radio transmit" test in Test menu, 20 MHz is used instead.

      Solution:
      40 MHz and 80 MHz bandwidth now works for the radio tests. Also fixed so it is not permitted to run the radio tests for other regulatory domain than US when lacking the unlock option "Unrestrict OBA radio". Before, the handset fallbacked to US when lacking "Unrestrict OBA radio" without the user being aware of it.

      125708 - Add WPA3-Enterprise parameter allowing SHA1

      Background:
      Some infrastructures still uses SHA1 for WPA3-Enterprise.

      125711 - Automatic upload of parameter definition file to DM

      Background:
      Uploading of parameter definition files to DM is carried out manually. It is a tedious job for the handset administrator to manage one file for each handset variant and at the same time the different versions of the files used for the different handset firmware versions.

      Solution:
      The handset now automatically uploads its current parameter definition file to DM. The handset administrator does no longer need to upload any parameter definition files (however it still supported for backward compatibility – when connected to a DM that does not support it).

      125766 - Change back WLAN location report format to legacy behavior

      Background:
      The location report format has in some special cases diverged from the legacy format. Just after restart the location report consisted of only one WLAN location, while in legacy there are always two, current and previous. Conform to legacy format of the alarm WLAN location report.

      Solution:
      Change to legacy WLAN location report format, i.e. always send two locations.

      125759 - Change text size for idle screen

      Background:

      Solution:
      The screen information is no longer mirrored.

      125758 - Fulfill Ray Baum's Act for Mitel PBX

      Background:
      In order to fulfill Ray Baum's Act for Mitel PBXs, E911 tracking need to be implemented. For this to work on a system level the handset must send out the active AP's BSSID in SIP invite and SIP invite response 200 OK message (for all calls)

      Solution:
      User parameter /VoIP/SIP/Register with SIP instance-id changed name to /VoIP/SIP/Emergency call location method and value 'Send BSSID in SIP invite' is added. When value 'Send BSSID in SIP invite' is set the active AP's BSSID is send in SIP invite and SIP invite response 200 OK for all calls

      125764 - Handset can restart when WiFi location, Airista flow or site survey is used

      Background:
      SSIDs on site are scanned when WiFi location, Airista flow or site survey is used. If there is a SSID on site with more than 32 characters the memory is overwritten and cause the handset to restart. The handset can also not parse special characters in SSIDs so a special character is interpreted as multiple characters. A memory leakage was also detected during testing that cause handset to restart when out of memory.

      Solution:
      SSID containing special characters or being longer than 32 characters will be labelled "<Unsupported>". Also fixed memory leakage.

      125769 - Handset reboots if lanpbx.cfg is received via DHCP

      Background:

      Solution:
      A file called "diagnostics.txt" is now available when the handset is connected over USB in File transfer mode. The file is generated (or updated) every time the Save logs functionality is either turned on or off.

      125707 - Improvements for handset parameter: transfer unlock file

      Background:
      When investigating problem on site, support can send an unlock file that is entered into handset parameter "transfer unlock file" in DM. This sets the handset in a development mode so it can be upgraded with a development SW. The development mode should be only used during debugging/test of fix since it is a security risk that the handset can be upgraded to an unsigned SW. To set back to normal operation a factory reset is required.

      Solution:
      When handset is in development mode, the handset can be restored to normal operation using the new "lock handset" option in admin menu without having to factory reset the handset.

      125310 - IP73 Missing device certificate

      Background:

      SCEP do no longer remove production certificate if not activated.

      125729 - Make handset more robust to gratuitous ARP from 00:00:00:00:00:00

      Background:
      It has been observed that the handset will sometimes receive gratuitous ARP responses from address 00:00:00:00:00:00 claiming the IP address used by the handset. If two such responses happen to be received within 10 seconds, the handset will surrender its IP address, which is the correct behavior according to RFC-3927 section 2.5. This will however result in a short loss of IP connectivity.

      Solution:
      In order to make the handset more robust under these circumstances, it will no longer release its IP address if an ARP response claiming the address comes from address 00:00:00:00:00:00.

      125727 - Make remote syslog messages available locally in the handset

      Background:
      Add support for storing the remote syslog data locally in the handset.

      Solution:
      Remote syslog now available along the other logs that can be retrieved via USB.

      125760 - Missing device certificate

      Background:
      SCEP removes production certificate on handset (if present) even though SCEP is not activated.

      Solution:
      SCEP do no longer remove production certificate if not activated.

      125789 - Monitoring of SIP registration

      Background:
      It has observed that the handset will not always re-register to the SIP server in time. The prerequisites for this to happen are not known.

      Solution:
      Extra monitoring of the SIP registration has been added. If the expiry time of a SIP registration is passed without any new registration being performed, the registration process will be reset and the handset will re-register.

      125765 - No audio for 2 seconds when calling PBX using ACD

      Background:

      Solution:
      2 sec. voice drop no longer existing when using ACD.

      125786 - Parameter migration of Wi-Fi security mode not working

      Background:
      The parameter migration feature in software versions 3.0.0-3.0.5 did not handle migration of the Wi-Fi Security Mode parameter correctly.

      Solution:
      When applying a template that was created either for a software version prior to 3.0.0, or a previous handset generation, some special care must be taken according to:
      1. Handset running software version between 3.0.0 and 3.0.4 must be upgraded to a later software version
      2. After the upgrade, the handset must either be factory reset, or the Security Mode parameter of the affected networks must be set to "Undefined" before the template is applied.

      125761 - Poor call quality when using Opus codec

      Solution:
      Data storage cannot be filled up by trace files anymore.

      125773 - Screen saver is not closed when removed from charger

      Background:
      Sometimes the handset is not responding when taking it out from the charger, no idle display is shown and pressing buttons do not affect anything. After a while the time in the screen saver was updated but the screen saver was not closed.

      Solution:
      The screen saver is closed and the handset does no longer freeze when removed from charger.

      125781 - Security mode changes to Open after SW downgrade

      Background:
      Downgrading from SW version 3.x.x to 2.x.x will cause WiFi connection loss if the parameter settings for security mode and/or EAP method has been changed, or if a factory reset has been performed, while on version 3.x.x. This due to changes to the mentioned settings are not migrated to the old/deprecated setting.

      Solution:
      Changes to Security mode and EAP method parameters will be migrated to the old/deprecated parameter (used in earlier SW version, prior 3.x). This will make it possible to downgrade to v2.x without losing WiFi connection.

      125778 - SFTP is turned off if save logs has expired

      Background:
      Using the functions Save for 10 minutes, Save for 4 hours etc there is a timestamp stored to keep track if we have passed that time if handset is turned off and after a while turned on again. If time has passed the intention is to stop saving log to flash but instead SFTP is turned off and handset reboots (it is a reboot parameter).

      Solution:
      If both save logs and SFTP functions are enabled at bootup and the time has expired for the save logs, sftp is not disabled.

      125770 - SIP INVITES not sent to the PBX

      Background:
      The communication between the handset and the PBX is interrupted, resulting in SIP calls not being established.

      Solution:
